Microsoft Lync Server (Mediation Role)

This template assesses the status and overall health of services as well as the performance of the Mediation Microsoft Lync Server.

Prerequisites: WMI access to the target server.

Credentials: Windows Administrator on the target server.

Monitored Components

Note:You need to set thresholds for these counters according to your environment. It is recommended to monitor these counters for some period of time to understand potential value ranges and then set the thresholds accordingly. For more information, see http://knowledgebase.solarwinds.com/kb/questions/2415.

Service: Lync Server Replica Replicator Agent

This component monitor returns the CPU and memory usage of the Lync Server Replica Replicator Agent. This service is used by the File Transfer Agent for replication configuration settings.

Outbound Calls: Current

This component monitor returns the total number of active calls going through the Mediation Server.

Outbound Calls: Active media bypass calls

This component monitor returns the total number of active calls going through Mediation Server that are in Media Bypass mode. Calls using Media Bypass use significantly fewer Mediation Server resources because the media is not flowing through the Mediation Server.

Inbound Calls: Current

This component monitor returns the number of inbound calls in progress.

Inbound Calls: Active media bypass calls

This component monitor returns the number of media bypass calls in progress.

Media Relay: Media Connectivity Check Failure

This component monitor returns the number of calls where media connectivity between the Mediation Server and the remote endpoints could not be established. The returned value should be as low as possible.

Health Indices: Load Call Failure Index

This component monitor returns the scaled index between zero and 100 that is related to all call failures due to Global Health Index as a heavy load.

Global Counters: Current audio channels with PSM quality reporting

This component monitor returns the total number of active channels that are having Phase Shift Modulation (PSM) quality reported. Calculating PSM quality has a processing overhead so this should be taken into account when measuring performance.

Total failed calls caused by unexpected interaction from the Proxy

This component monitor returns the number of calls that failed because of an unexpected response from the Front End Server. The returned value should be as low as possible.

Total failed calls caused by unexpected interaction from a gateway

This component monitor returns the number of calls that failed because of an unexpected response from a gateway peer. The returned value should be as low as possible.
